Hearing someone say my Twitter and Tumblr username out loud is pretty much a spiritual experience.

I can't overstate how much this quote means to me. So many years ago I came up with the username Leapfrog for a wiki page. It's based on a method used in numerical analysis and it is used in numerical weather prediction models, which is what I was working on at the time. Not much later, I started my first public social media profile, but Leapfrog was already taken. So I added Fuzzy. It's based on fuzzy logic, so again something I was just learning about. Whereas Boolean logic is based on only two truth values,
Fuzzy logic [...] is a special many-valued logic which aims at providing formal background for the graded approach to vagueness.

That is how I became FuzzyLeapfrog, or simply Fuzzy.
Both words capture my nature and soul very well. I always try to find a numerical solution, while acknowledging that the world is more complex and vague than that.
So I've been called Fuzzy online for over a decade now, but gradually Fuzzy has also found its way into offline interactions. It's not just about me though. So many people I meet offline are people I met online and we very often address each other with our online names anyway. This has brought me so much joy and probably caused a lot of confusion for people who are unfamiliar with our online names or even the concept of online names.
Anyway, it doesn't matter how often I hear it, having someone acknowledge our online connection by calling my Fuzzy loudly offline is an endless source of inner joy. I am Fuzzy.
